Brexit, Northern Ireland and WooCommerce Shipping Zones

Resources

This use-case will focus on the recent changes (as at January 2021) related to Brexit, specifically in terms of configuring different shipping zones in WooCommerce for Nothern Ireland. These shipping zones will focus on Nothern Ireland’s counties, rather than using wildcard shipping zones.

For more in-depth information on how Brexit affects WooCommerce stores, please review the following guides first:

Scenario

John, a shop owner based in London sells custom motorbikes to the Republic of Ireland. Due to the recent changes in duties & tarrifs in Brexit, John needs to configure a separate shipping zone for Northern Ireland due to the following reasons:

The costs associated with shipping to Northern Ireland are significantly different that the rest of the United Kingdom

Add Northern Ireland as Standalone Country

↑ Back to top

While it’s not something we recommend as Northern Ireland is part of the United Kingdom, certain shop owners might prefer to display Northern Ireland as its own standalone country. To do that, please follow these steps:

Install a plugin that allows shop owner to add code snippet (e.g. Code Snippets)
In the Code Snippets settings, add the following custom code:

// Add Northern Ireland to the list of countries in WooCommerce
add_filter('woocommerce_countries', 'add_northern_ireland_country');

function add_northern_ireland_country($countries) {
    $countries['NIR'] = __('Northern Ireland', 'woocommerce');
    return $countries;
}

// Add Northern Ireland to the list of allowed countries for shipping
add_filter('woocommerce_shipping_zone_postcodes', 'add_northern_ireland_shipping_zone', 10, 3);

function add_northern_ireland_shipping_zone($postcodes, $instance_id, $zone_id) {
    if (!is_array($postcodes)) {
        $postcodes = array();
    }
    $postcodes[] = 'NIR';
    return $postcodes;
}

// Ensure Northern Ireland is available in the billing and shipping country dropdowns
add_filter('woocommerce_get_country_locale', 'add_northern_ireland_country_locale');

function add_northern_ireland_country_locale($locales) {
    $locales['NIR'] = array(
        'postcode' => array(
            'required' => false,
            'hidden' => false,
        ),
        'state' => array(
            'required' => false,
            'hidden' => false,
        ),
        'city' => array(
            'required' => true,
            'hidden' => false,
        ),
    );
    return $locales;
}

3. Navigate to the Shipping Locations settings located under WooCommerce > Locations

4. Locate “Northern Ireland” and add the respective counties

Please note: If your store allows customers to select between both Northern Ireland and the United Kingdom during checkout, we recommend removing the Northern ireland counties from the United Kingdom. This is possible by selecting “United Kingdom” in step #4 above and hovering over each matching county to delete.
